Question

我正在使用laravel 5.4。

我正在使用php artisan list，但收到以下错误：

C:\Users\admin\Desktop\Coding Projects\demo_laravel>php artisan list
PHP Fatal error:  Cannot declare class TestCommandRun, because the name is already in use in C:\Users\admin\Desktop\Coding Projects\demo_laravel\app\Console\Commands\TestCommandRun.php on line 109

In TestCommandRun.php line 109:

  Cannot declare class TestCommandRun, because the name is already in use

我的命令名称正确：

class TestCommandRun extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'TestCommandRun:run';

在我的Kernel.php中，我已将其添加到$commands部分：

protected $commands = [
    '\App\Console\Commands\TestCommandRun',        
];

为什么我收到上述错误消息的任何建议？

看起来你有两个具有相同类名using System; using System.Collections.Generic; namespace KvpSequence { class Program { const int numberOfSequences = 4; // each sequence is a set of 4 ints between 1 and 5 static void Main(string[] args) { List<KeyValuePair<int, int>> sequence = new List<KeyValuePair<int, int>>(numberOfSequences * 4); Random rand = new Random(); for (int i = 0; i < numberOfSequences; ++i) { var indexToSet = rand.Next(0, 4); for (int j = 0; j < 4; ++j) sequence.Add(new KeyValuePair<int, int>(rand.Next(1, 6), j == indexToSet ? 1 : 0)); } foreach (var kvp in sequence) Console.WriteLine(kvp); } } }的命令。所以，你需要删除一个。

此后运行TestCommandRun命令也是个好主意。

无法声明类＆＃39; TestCommandRun＆＃39;，因为该名称已被使用
